Leonardo Da Vinci
Italian High Renaissance Painter and Inventor, 1452-1519
Florentine Renaissance man, genius, artist in all media, architect, military engineer. Possibly the most brilliantly creative man in European history, he advertised himself, first of all, as a military engineer. In a famous letter dated about 1481 to Ludovico Sforza, of which a copy survives in the Codice Atlantico in Milan, Leonardo asks for employment in that capacity. He had plans for bridges, very light and strong, and plans for destroying those of the enemy. He knew how to cut off water to besieged fortifications, and how to construct bridges, mantlets, scaling ladders, and other instruments. He designed cannon, very convenient and easy of transport, designed to fire small stones, almost in the manner of hail??grape- or case-shot (see ammunition, artillery). He offered cannon of very beautiful and useful shapes, quite different from those in common use and, where it is not possible to employ cannon ?? catapults, mangonels and trabocchi and other engines of wonderful efficacy not in general use. And he said he made armoured cars, safe and unassailable, which will enter the serried ranks of the enemy with their artillery ?? and behind them the infantry will be able to follow quite unharmed, and without any opposition. He also offered to design ships which can resist the fire of all the heaviest cannon, and powder and smoke.
The large number of surviving drawings and notes on military art show that Leonardo claims were not without foundation, although most date from after the Sforza letter. Most of the drawings, including giant crossbows (see bows), appear to be improvements on existing machines rather than new inventions. One exception is the drawing of a tank dating from 1485-8 now in the British Museum??a flattened cone, propelled from inside by crankshafts, firing guns. Another design in the British Museum, for a machine with scythes revolving in the horizontal plane, dismembering bodies as it goes, is gruesomely fanciful.
Most of the other drawings are in the Codice Atlantico in Milan but some are in the Royal Libraries at Windsor and Turin, in Venice, or the Louvre and the École des Beaux Arts in Paris. Two ingenious machines for continuously firing arrows, machine-gun style, powered by a treadmill are shown in the Codice Atlantico. A number of other sketches of bridges, water pumps, and canals could be for military or civil purposes: dual use technology.
Leonardo lived at a time when the first artillery fortifications were appearing and the Codice Atlantico contains sketches of ingenious fortifications combining bastions, round towers, and truncated cones. Models constructed from the drawings and photographed in Calvi works reveal forts which would have looked strikingly modern in the 19th century, and might even feature in science fiction films today. On 18 August 1502 Cesare Borgia appointed Leonardo as his Military Engineer General, although no known building by Leonardo exists.
Leonardo was also fascinated by flight. Thirteen pages with drawings for man-powered aeroplanes survive and there is one design for a helicoidal helicopter. Leonardo later realized the inadequacy of the power a man could generate and turned his attention to aerofoils. Had his enormous abilities been concentrated on one thing, he might have invented the modern glider.

(May 12, 1858 - September 27, 1938) was a respected and commercially successful Canadian painter. He worked in oils and watercolors, often depicting scenes of rural life in Canada. He was highly influenced by the French Barbizon school of painting.
Horatio Walker was born in 1858 to parents Thomas and Jeanne Maurice Walker. Thomas Walker emigrated in 1856 from Yorkshire, England, to Listowel, Ontario, with his wife of French and English heritage. Having some wealth, Thomas purchased land for lumber in Midwestern Ontario and Horatio was raised in relative comfort. His interest in art may originate from his father who crafted small figures as a hobby, and both his father and the local school teacher encouraged drawing as a pastime.
In 1870, on Walkeres 12th birthday, his father brought him to Quebec City, Quebec, for the first time. His father made occasional business trips to the city as part of his timber business. During this sojourn, they visited the Île d'Orleans, in search of pine timber. Walker made subsequent visits to Quebec City during the following years. His formal schooling ended at the Listowel Public School in 1872; he never went on to pursue formal academic training in art. At the age of 15, Walker moved to Toronto, Ontario to apprentice with the photographic firm Notman and Fraser. It was a fortunate opportunity, as several successful artists worked also there; Walker learned watercolour from Robert Gagnon, miniature portrait painting from John Fraser, and painting from Lucius OeBrien and Henri Perre.Carnicero, Antonio
Spanish, approx. 1748-1814
Painter and draughtsman, son of Alejandro Carnicero. He arrived at the Court in Madrid with his father in 1749 and took part in the competitions held by the Real Academia de S Fernando, winning second prize in 1769 with the Coronation of Alfonso XI and Queen Mary in the Monastery of Huelgas de Burgos (Madrid, Real Acad. S Fernando, Mus.). In 1760 he won a scholarship to Rome, subsequently winning prizes from the Accademia di S Luca. On his return to Madrid in 1766 he worked as a portrait painter, producing works such as the portrait of Do?a Tomasa de Aliaga, Widow of Salcedo (Madrid, Prado). In 1788 he was elected an honorary member of S Fernando. Under the protection of the Spanish prime minister, Manuel Godoy, Prencipe de la Paz, whom he painted on several occasions , and after painting the portraits of Charles IV and Maria Luisa (both Madrid, Monasterio de la Encarnacien), he was appointed Pintor de Cemara in 1796. In 1798 he applied unsuccessfully for the post of drawing-master to the Prince of Asturias, the future Ferdinand VII, although by 1806 he was teacher of the Infante Princes. He was a refined draughtsman and prepared illustrations for the editions of Cervantes's El ingenioso hidalgo Don Quixote de la Mancha published by the Real Academia Espa?ola (Madrid, 1780; 1782). He also made the drawings for the handsome engravings (Madrid, Calcografra N.) of the Real Picadero (Royal Riding School). In addition to his portraiture, which displays a talent for realism and wit, although at times combined with slightly garish colours, Carnicero executed attractive and descriptive costumbrista paintings, depicting everyday life, popular gatherings and hunting scenes, for instance Duck Shooting on the Albufera, Valencia Edward Theodore Compton
(July 29 1849 - March 22 1921) was an English-born, German artist, illustrator and mountain climber. He is well-known for his paintings and drawings of alpine scenery, and as a mountaineer made 300 major ascents including no fewer than 27 first ascents.
Compton was born in Stoke Newington in London, the son of Theodore Compton, an art-loving insurance agent, and grew up in a deeply religious Quaker household. He attended various art schools, including, for a time, the Royal Academy in London, but otherwise he was mainly self-taught in art.
